Wasn't doing anything useful
It actually converted any non-zero alpha to full opaque
almost the opposite of what it claimed to do
Simplify the option set by removing useless options rather than fix it

AlphaCoverageThresholds was accidentally enabled for all textures with thresholds = {0,0,0,1}
add new Texture bool bDoScaleMipsForAlphaCoverage
to make toggling coverage processing very clear
on old Textures that don't have the bDoScaleMipsForAlphaCoverage field, we can infer the correct value except in the case that threshold = {0,0,0,1} , in that case it's impossible to tell if it's wanted or not. There we look up a config value "EnableLegacyAlphaCoverageThresholdScaling"
Current config has EnableLegacyAlphaCoverageThresholdScaling=1
so the legacy bad behavior is maintained

-Add mechanism for ITextureFormat to have a generic and private "FormatSettings" block that can be global, but also exported with a texture build action and applied when a texture build is executed remotely. Also ensure that ChildTextureFormat is able to split and store/read the format settings for Child & Base format as separate sub-items.
-Allow the PS5TextureBuildWorker to compile in Oodle if the plugin is present and enabled.

This has a single use case: We build streaming virtual textures from runtime virtual textures and we want to ensure the format doesn't change just because the alpha channel is all 1.

Downscaling will keep texure size divisible by 4 so they can still be compressed

- An additional bit in the FTexturePlatformData next to the Cubemap bit is used to indicate whether the structure contains non-default OptData. Contents of the OptData field is only serialized when that bit is set.
- Platforms which do no make use of OptData will automatically not have that data in their cooked byte stream, as the values will remain default. Platform that do set those values will have the data included and the bit set.

Runtime virtual texture uses streaming virtual texture to fill pages at distance
We recently moved to YCoCg encoding in the compressed base color texture to address visual quality issues
The runtime virtual texture used a per block scaling, but the offline generated streaming texture didn't
The offline texture looks much worse without the block scaling so that we see color artifacts in the distance before this change
